Keyword: Enter the text shortcut you want to use for the search engine. You can use the keyword to quickly access the search engine via the address bar.

URL: Enter the web address for the search engine. To find the web address:

Go to the search engine you want to add.

Do a search.

Copy and paste the web address of the search results page into the URL field. Keep in mind that the URL for the search results page is different from the website URL. For example, while you'd go to http://www.google.com to access Google, the URL you'd add here is for the search results page if you've searched for "xyz," http://www.google.com/search?q=XYZ.

Replace the search term in the URL with %s. To continue the Google search engine example, you'd end up with http://www.google.com/search?q=%s as your final search engine URL. When you type a search in the address bar, %s will automatically be replaced by your search term.

Note: Make sure you include %s in the URL. Otherwise, you won't be able to set this search engine as your default search engine.
